Concept:Water scarcity means the demand for water exceeds the available safe supply. It makes water unsafe for basic needs like drinking and cooking.
Explanation:Water scarcity occurs when an area does not have enough clean water for essential uses.
The main sign is that the available water is contaminated or unsafe for drinking and cooking.
Contaminated water can cause diseases like diarrhea, cholera, and typhoid.
Forced use of poor-quality water shows scarcity, even if some water is physically present.
Factors like population growth, agriculture, and industry increase water demand.
Scarcity can also force people to travel far to collect water, especially women and children.
Therefore, the key indicator of water scarcity is when the water received is not safe for drinking and cooking.
